This solar fan is recommended for installation on any low slope or commercial flat roof. Comes complete with curb base. Panel can be tilted to maximize sun exposure. Panel tilts from 0 to 60° in 5° increments. Available in 30 watt size only.

The more intense the sun shines, the faster the SunRise runs, keeping your attic from overheating.

This unique, solar powered vent fan pulls the heat right out of your attic; it's so effective it can lower attic temperatures by as much as 50°. This means less heat dissipating back into your living area, less drain on your air conditioning system, and less cost to you. In fact, up to 30% less money spent on air conditioning costs alone.

In the wintertime, the solar attic fan helps equalize the temperature between the attic inside and the outside air. This dramatically reduces the risk of ice dams forming at the eaves, a feature that could save you thousands.

It reduces moisture build-up and prolongs the life of your roof. Even in newer homes that use vapor barriers, moisture can still sneak into the attic and condense on framing boards, roof decking, and insulation. The problem may be even worse in older homes that have settled and developed cracks or air leaks around bathroom exhaust fans or light fixtures. The attic fan forcibly expels this warm, moist air, helping prevent the growth of mold and mildew, and significantly reducing the chance of rotting the roofing materials.

Just one Solar Fan is powerful enough to protect an entire home, it uses the most advanced solar panels to collect and deliver power directly from the sun to our highly efficient 12-volt DC motor inside the power vent. With its 12, balanced-hub, aluminum fan blade, the fan forcibly expels hot air, providing fresh, cool air to keep your attic from overheating!

The tough, weather-resistant panels collect solar energy even in reduced light and poor weather conditions and provide maximum cooling effect when its needed most--in the middle of the day. The solar attic fans operate without fuel, waste, or pollution and are wind, hail, and impact resistant.

ThermostatModel FB 1600 FT comes with a thermostat and is recommended for dry climates.The Fixed Thermal Switch is designed to turn the fan:ON: 80° FOFF: 65° F(+/-7°)

Example: Attic temperature rises to 80° and fan turns on. Once it cools to 65° the fan will shut off. If evening comes and temp does not fall below 65° to reset the switch, then the unit will start the next morning at sunrise and continue to cool the attic. However, if the attic temp falls below 65° at night, then the switch will shut off and will not turn the unit on again until attic temp reaches 80°.

Installer: This fan will not run unless the ambient (air) temperature is at or near 80°. To test fan for operation, disconnect red wire from thermal switch and attach directly to motor. Make sure solar panel is exposed to sunlight.
